From 482c119186987110bfccf705a5ac75d399b08766 Mon Sep 17 00:00:00 2001 From: "brian m. carlson" Date: Thu, 11 Feb 2021 02:08:03 +0000 Subject: gpg-interface: improve interface for parsing tags We have a function which parses a buffer with a signature at the end, parse_signature, and this function is used for signed tags. However, we'll need to store values for multiple algorithms, and we'll do this by using a header for the non-default algorithm. Adjust the parse_signature interface to store the parsed data in two strbufs and turn the existing function into parse_signed_buffer. The latter is still used in places where we know we always have a signed buffer, such as push certs. Adjust all the callers to deal with this new interface.
